| abstract |
The invention provides compositions and methods for generating new tissue on a surface, e.g., a surface of damaged or lost tissue, of a structure or organ in a mammal, The methods involve applying a thin layer of a liquid hydrogel-cell composition to the surface; and allowing the liquid hydrogel-cell composition to solidify, thereby forming a matrix that enables the tissue precursor cells to grow and generate new tissue. The surface can be internal, e.g., the surface of an organ or the internal surface of a blood vessel, or external, e.g., skin. |
